Pre-Charge Tank Connection (Figure 4)

1.Install two tees in the pump discharge port (see Figure 4). The pipe size must be at least as large as the discharge port.

2.Run a pipe or reinforced hose from one arm of the first tee to the port on the pre-charged tank.

3.Connect the other end of the discharge tee to your plumbing system. Cap the tee with a threaded plug or a pressure gauge.

4.Check the pre-charge of air in the tank with an ordinary tire gauge. The pre-charge should be 2 PSI less than the cut-in setting of the pump’s pressure switch. The pre-charge is measured when there is no water pressure in the tank. Your new pump has a 30/50 PSI switch, so adjust the tank pre-charge pressure to 28 PSI.

Congratulations! You have just completed the tank connection for your jet pump. Please go to Page 7 for electrical hookup.

Standard Tank Connection (Figure 5)

1.Install one tee in the pump discharge port (see Figure 5).

2.Run a pipe from the pump discharge port to the inlet port of your tank. The pipe size must be at least as large as the discharge port.

3.Install a tee in the suction pipe near the pump. Install a reducer bushing down to 1/8” NPT in the tee. Run tubing from the tee to the port on the AVC mounted on the tank. Seal all joints with Teflon™ tape. See instructions provided with the tank and the AVC for details.

Congratulations! You have just completed the tank connection for your jet pump. Please go to Page 7 for electrical hookup.

Sealing Pipe Joints

Use only 1Teflon™ tape or Teflon™ based joint compounds for making all threaded connections to the pump itself. Do not use pipe joint compounds on plastic pumps: they can react with the plastic in pump components. Make sure that all pipe joints in the suction pipe are air tight as well as water tight. If the suction pipe can suck air, the pump will not be able to pull water from the well.
